Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed in a hand washing section of a low tank with hand washing in a flush toilet, and mixes a chemical (such as an aromatic, a cleaning agent, or a bactericide) with water supplied from a caran above the hand washing section. The present invention relates to a medicine ejection container suitable for performing the above.

[0002]

2. Description of the Related Art As a conventional container for dropping fragrance for a flush toilet, one described in Japanese Utility Model Publication No. 6-34457 is known. In this container, the water injected from the curan is guided to the mixing case for mixing the aromatic cleaning liquid and the water, and the float valve is pushed up in response to the rise in the water level in the mixing case to release the bottle of the aromatic cleaning liquid. A hole is opened, and at the same time, the pressurized air in the mixing case is sent into the bottle. Then, when the water injection from the curan stops, the float valve is lowered, and the aromatic cleaning liquid is discharged from the bottle into the mixing case. Then, when water injection from the curan starts again, the aromatic cleaning liquid mixed with water in the mixing case is drained from the drain port of the mixing case to the hand washing section.

[0003]

However, the container for dropping aromatic drops described in Japanese Utility Model Publication No. 6-34457 has a problem in that it is structurally complicated and the production cost is high. Furthermore, there is a problem that the float valve is easily clogged because the fragrance cleaning liquid is easily solidified. In addition, the replacement of the aromatic cleaning liquid in the bottle with the air in the mixing case often does not proceed smoothly due to fluctuations in water pressure and the like, and there is a problem that the discharge amount of the aromatic cleaning liquid is not constant.

[0004] On the other hand, an object of the present invention is to provide a medicine ejection container capable of stably ejecting a fixed amount of medicine with a relatively simple mechanism that does not require manufacturing costs.

[0005]

In order to achieve the above-mentioned object, the present invention relates to a medicine discharging container having a water storage tank on a medicine tank, wherein the water storage tank is provided with a water inlet and a water outlet. The medicine tank has a medicine ejection port for ejecting medicine, and a pressure applied in accordance with the amount of water stored in the water storage tank to deform and change the pressure in the medicine tank, thereby ejecting medicine from the medicine ejection port. Or an elastic portion for introducing air into the medicine tank is provided, and a temperature change prevention structure is provided to prevent the temperature in the medicine tank from being changed by water supplied from above the water storage tank. Provided is a medicine ejection container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. In the drawings, the same reference numerals indicate the same or equivalent components.

FIG. 2 shows a medicine ejection container 1 according to one embodiment of the present invention.
FIG. 1 is a perspective view of 00A, and FIG. 1 is a sectional view for explaining the operation of the medicine ejection container 100A.

As shown in FIG.
A comprises a medicine tank 2 for holding a medicine A such as a fragrance cleaning liquid for toilets, and a water storage tank 1 stacked on the medicine tank 2.

An inlet 3 is provided at the top of the water storage tank 1, and when the medicine discharge container 100A is placed on the hand washing section 20 of the low tank with hand washing of the flush toilet, water is supplied from the callan above the water storage tank 1. The water W enters the water storage tank 1 as shown by the arrow in FIG. Further, the water storage tank 1 is provided with a drain port 4 for draining the water W stored in the water storage tank 1 from the bottom of the water storage tank 1 to the outside. This drain port 4 is always open. The size and number of the drainage ports 4 are appropriately determined so that even if the water entering the water storage tank 1 from the injection port 3 continues to be drained from the drainage port 4, the water is still stored in the water storage tank 1.

A water guiding wall 8 is provided on the bottom peripheral edge of the water storage tank 1 so as to cover the side surface of the medicine tank 2. The water guide wall 8 is provided as a water guiding structure for preventing the chemical tank 2 from being exposed to the water W supplied from above the water storage tank 1, and thereby, the water guide wall 8 is provided from the cull above the water storage tank 1. The supplied water W prevents the temperature in the medicine tank 2 from changing.

On the other hand, the medicine tank 2 is provided at its top with an elastic portion 6 made of a dome-shaped rubber member which is deformed by a pressing force corresponding to the amount of water stored in the water storage tank 1.
The medicine tank 2 itself is formed so as not to be substantially deformed so that the pressure in the medicine tank 2 is increased by the deformation of the elastic portion 6.

At the bottom of the medicine tank 2, a medicine ejection port 5 for ejecting medicine A is formed in a nozzle 7 projecting downward. The medicine tank 2 communicates with the outside only at the medicine discharge port 5. The medicine A is held at the medicine ejection port 5 by surface tension or by a negative pressure in the medicine tank 2 so that the medicine A does not continue to be dripped from the medicine ejection port 5 and is not consumed unnecessarily. Therefore, the opening area of the medicine ejection port 5 is appropriately determined according to the properties of the medicine A.

Further, the medicine tank 2 is provided with a foot 13 for preventing the main body 2a of the medicine tank storing the medicine A from being exposed to the water flowing through the hand washing section 20.

As a method of using the medicine ejection container 100A, in a state where the medicine A is filled in the medicine tank 2, the medicine ejection container 100A is first placed on the hand washing section 20 of the low tank with hand washing of a flush toilet. In this case, the inlet 3 of the water storage tank 1 is located below the callan,
The tip of the nozzle 7 fits into the water supply port 21 of the low tank that is open to the hand washing section 20 (FIG. 1).
(A)).

When water W is supplied from the callan as shown by the arrow, the water is drained from the drain port 4 and the water storage tank 1 is discharged.
The water is stored inside (Fig. 1 (a)). At this time, the water that has been supplied from the caran and that has come off from the inlet 3 flows through the peripheral wall 1a of the water storage tank and the water guide wall 8 into the water supply port 21 of the low tank with a strong force, and also from the drain port 4. The drained water also flows through the water guide wall 8 and into the water supply port 21 of the low tank. At this time, the main body 2 of the medicine tank
a is not exposed to water.

The elastic portion 6 is gradually deformed by the weight of the water stored in the water storage tank 1. When the amount of water stored in the water storage tank 1 exceeds a certain amount, the elastic portion 6 is crushed, and the internal pressure of the medicine tank 2 is reduced. The medicine A is ejected from the medicine ejection port 5 in a fixed amount. The discharged medicine A enters the low tank from the water supply port 21 together with the water W in the supply water (FIG. 1).
(B)).

When a predetermined amount of water is supplied from the callan, the water supply from the callan stops, but the water W stored in the water storage tank 1 is drained from the drain port 4 thereafter. Drain 4
The water flowing out of the main body 2a of the chemical tank is not exposed to water through the water guide wall 8 and into the low tank through the water supply port 21.

When the water W stored in the water storage tank 1 flows out, the force with which the water storage tank 1 presses the elastic portion 6 becomes weak, and the elastic portion 6 recovers its original shape. At this time, since the inside of the medicine tank 2 has a negative pressure, the air B enters the medicine tank 2 from the medicine discharge port 5 as shown by the arrow, and the inside of the medicine tank 2 returns to normal pressure, or a state of a weak negative pressure. (FIG. 1 (c)).

Thereafter, each time water is supplied from the curan, this action is repeated, and the medicine A is dropped into the low tank by a fixed amount.

With respect to the medicine ejection container 100A, the water guide wall 8 is not provided at the peripheral edge on the bottom side of the medicine tank 2;
As shown in (a), when the water W supplied from the curan and removed from the inlet 3 or the water discharged from the drain 4 flows through the main body 2a of the chemical tank, the supplied water W In winter, for example, when the temperature of the toilet is generally lower than the room temperature in the toilet, the inside of the medicine tank 2 is temporarily cooled by supplying water. Next, as the water W is stored in the water storage tank 1, the elastic portion 6 is crushed as described above, and a predetermined amount of the medicine A is ejected from the medicine ejection port 5 (FIG. 7).
(B)). When the water supply from the callan stops, the elastic part 6 recovers to its original shape, but thereafter, the temperature of the medicine tank 2 is gradually warmed because the room temperature in the toilet is higher than that of the cooled medicine tank 2, and the medicine tank is gradually warmed. Since the air C in the container expands and becomes in a pressurized state, a dripping out of the setting occurs for the medicine A.
(C)). Such dripping out of the setting becomes remarkable especially when the medicine tank 2 is sufficiently cooled to room temperature by continuously using the toilet.

However, the medicine ejection container 10 described above
According to 0A, the water guide wall 8 prevents the chemical tank 2 from being exposed to the water W supplied from above the water storage tank 1,
Since the structure is such that the temperature change of the medicine tank 2 is prevented, it is possible to prevent such a dripping of the medicine outside the setting.

FIG. 4 is a perspective view of a medicine ejection container 100B according to another embodiment of the present invention, and FIG. 3 is a sectional view showing the operation thereof. The medicine ejection container 100B is different from the medicine ejection container 100A shown in FIGS. 1 and 2 in that a water guiding wall 8 is provided on the bottom peripheral edge of the medicine tank 2 instead of the medicine tank 2 as a water guiding structure. Between water tank 1
An umbrella-shaped member 9 that covers the medicine tank 2 is provided.
When the umbrella member 9 is provided in this manner, the water W supplied from above the water storage tank 1 and removed from the inlet 3 and the water discharged from the drain port 4 flow through the umbrella member 9 and flow through the umbrella member 9. Can be prevented from being exposed to water.
The liquid dripping outside the setting due to the temperature change can be prevented.

FIG. 3 shows a structure in which the umbrella member 9 is fitted as a separate member between the medicine tank 2 and the water storage tank 1, but the umbrella member 9 is stored in the water storage tank 1. The structure attached to the water storage tank 1 or the chemical tank 2 may be used as long as the drainage of the water from the drain port 4 is not hindered and the chemical tank 2 is prevented from being cooled by being exposed to water.

In addition, in the present invention, the water guiding structure is such that the upper surface and the periphery of the medicine tank 2 are covered by the bottom surface of the water storage tank 1 as in a medicine ejection container 100C shown in FIG. The water storage tank 1 may be formed sufficiently large with respect to the tank 2 so that the medicine tank 2 is not exposed to water supplied from above the water storage tank 1.

FIG. 6 is a sectional view of a further different medicine ejection container 100D of the present invention. This medicine ejection container 100D
Is a double-walled heat-insulating structure of the main body 2a of the chemical tank in order to prevent the temperature inside the chemical tank 2 from being changed by water supplied from the curran above the water storage tank 1. It is.

In addition, as the heat insulating structure, the chemical tank 2
May be covered with a heat insulating material such as a foam made of polyethylene, styrene, or the like.

As described above, according to the medicine ejection container of the present invention, the medicine A can be easily and simply kept in the low tank by a simple mechanism using water injection from the caran without using a valve element such as a float valve. It can be added dropwise by volume. Furthermore, since a temperature change prevention structure is provided for preventing the temperature in the chemical tank 2 from changing due to the water supplied from the curran above the water storage tank 1, the temperature between the supplied water and the toilet room is reduced. Even if the temperature difference is large, a certain amount of drug A
Unnecessary dripping after dropping can be prevented.

In the medicine ejection container of the present invention, as shown in FIGS. 1 and 3, when the tip of the nozzle 7 is fitted into the water supply port 21 of the low tank which is open to the hand washing section 20, the low tank Since the medicine A is directly dropped into the inside, the hand washing unit 20 is not stained with the medicine A.

The medicine ejection containers 100A, 100B, 100
The water storage tank 1 and the chemical tank 2 constituting C and 100D can be easily manufactured using a plastic molded body as a constituent member.

The medicine ejection container of the present invention can take various other modes. For example, a water guiding structure for preventing the medicine tank 2 from being exposed to the water W supplied from above the water storage tank 1 to one medicine ejection container, and preventing the temperature in the medicine tank 2 from changing. It may be provided with both a heat insulating structure.

The water storage tank 1 can store water by supplying water from a caran, and as long as the stored water can be discharged by stopping the water supply, the shape of the water storage tank 1 itself is not particularly limited. The shape and the like can be appropriately determined.

The medicine tank 2 may be provided with an openable and closable opening for refilling the medicine.

When the legs 13 of the medicine tank 2 are formed long and the medicine ejection container 100A is placed on an arbitrary plane, and the medicine ejection port 5 is not attached to the plane, the hand washing section 20 of the flush toilet can be used. When the medicine ejection container 100A is placed on the low tank, it is not necessary to align the medicine ejection port 5 with the water supply port 21 of the low tank. Therefore, even when the water supply port 21 of the low tank is not provided directly below the callan, the medicine can be discharged by the water supply from the callan.

As the elastic portion 6, various elastic members other than the dome-shaped rubber member can be used as long as the elastic portion 6 is deformed by an increase in the pressing force and is restored by a decrease in the pressing force.
For example, a bellows made of plastic, a coil spring made of metal, or the like may be used.

Flush the toilet repeatedly every 30 minutes (flush)
Water was supplied from the curan to the raw tank, and the drug was dropped into the raw tank. At this time, the weight of the drug in the drug tank was measured for each flash 100, and the average value of the drop weight of the drug per flash was determined.

FIG. 8 shows the results. From FIG. 8, it can be seen that according to the medicine ejection container of this embodiment, the drop amount of medicine per flash is stable regardless of the difference between the room temperature and the water temperature.

Example 2 In place of the medicine ejection container shown in FIG. 1, the medicine ejection container shown in FIG. 3 (capacity of the medicine tank: 100 mL) was used. The average was determined. FIG. 8 shows the results. From FIG. 8, it can be seen that even with the medicine ejection container of this embodiment, the drop amount of the medicine per flash is stable regardless of the difference between the room temperature and the water temperature.

Comparative Example 1 In place of the medicine ejection container of FIG. 1, the medicine ejection container of FIG. 7 (capacity of the medicine tank: 100 mL) was used. The average was determined. FIG. 9 shows the results. From FIG. 9, according to this medicine ejection container, when the temperature difference between the medicine tank room temperature and the water temperature is 13 ° C., it is 1 more than when the temperature difference is 2 ° C.
It can be seen that the amount of drug dropped per flash is about 1.5 times or more, and the difference between room temperature and water temperature causes the amount of drug dropped greatly from the set value, and the drug is consumed more than necessary. .

[0039]

According to the medicine ejection container of the present invention, a fixed amount of medicine can be stably ejected by a relatively simple mechanism that does not require manufacturing costs. In particular, even when the difference between the room temperature and the water temperature is large, the predetermined ejection amount can be maintained, so that unnecessary consumption of the medicine can be prevented.
